Rating: 5/5 Purchased by Mistake March 31, 2017 I purchased the PC3-8500 by mistake. I notified OWC of my problem and they emailed me what I needed to get my refund. I received the package and quickly put it back in the mail. Once OWC received the shipment, they reversed the payment, and my refund was in my account the same day.

Rating: 5/5 is like i bought a new computer March 31, 2017 I have a macbook pro 13 mid 2010 that I was thinking of switching to a new one, but with this upgrade I think my old computer has rejuvenated. If you buy from Chile, like me, be patient because once in Chile it took more than 1 month to arrive.

Rating: 5/5 Perfect March 31, 2017 Very simple steps to follow in order to replace, no need to be a computer geek....I believe that anyone capable of reading and following instructions would be able to do it.

My macbook did indeed recognise the 16GB even though Apple states that the computer has a max of 8GB. I am very happy with the new specs on my machine and would recommend this easy upgrade to anyone that currently does not have the max 16GB already installed.

Rating: 5/5 Installed in 15 minutes March 25, 2017 Of course, having been invited by MacSales to write a review before the goods arrived, it was inevitable that the day after writing it, the two 8GB memory chips for my MacBookPro Mid 2010 arrived the next day.

The packaging is good, protecting already well packed chips with a stiff padded plastic wallet. The chips escaped French import duty, probably because the amount due was less than it would cost to collect.

It took 5 minutes to unscrew the back off the Macbook and after spudging up the battery connector for safety, a further 2 minutes to snap the old 2 x 4GB memory chips out and drop the new ones in. I spent 3 minutes reconnecting the battery and vacuuming up old dust and particles before screwing the back on again.

Within 15 minutes of starting, the MBP was up and running and a quick check in "About This Mac" showed that both new chips were recognised. To the best of my knowledge, this is the only source of functional 8GB chips for this model of MBP and anyone interested may safely ignore any warnings they read that 2 x 4GB chips is the maximum that the mid 2010 MBP can handle.

I don't have any strict benchmark checks to run comparisons before and after and this will come with experience. I expect to see faster performance in Photoshop especially with less switching between memory and hd. The Activity Monitor shows CPU usage much lower than before, but of course, this is in % and the capacity is now double. Since I installed Sierra, the fan had been coming on a lot, but so far, one day on, it has not cut in once.

My 13 inch MBP mid 2010 is a work-horse (graphics and e-book formatting) and travels a lot, whilst its 15inch retina stays unscratched at home. Compared to its original 4GB memory and 250GB spinning hard drive, it now has 16GB memory and a 1TB SSD. I am extremely happy with this latest upgrade which is a lot cheaper than buying a new model.

Rating: 5/5 Easy Memory Upgrade March 20, 2017 I upgraded memory from 2GB to 16GB on a mid-2010 MacBook . The information you provided was extremely helpful, and accurate. The first issue to be resolved was whether this particular MacBook could accommodate 16GB . . . your information said it could, and that was correct. Next, your video led me step-by-step through the upgrade process. The instructions were very clear and accurate.

I will definitely call on you again for my next Mac need.

Rating: 5/5 Excellent!! February 2, 2017 I was very sceptical going for this upgrade to 16GB in my Mid-2010 MBP. I have been reading about overheating issues in many forums. I had a chat with the customer service in this website and they assured me that it should work fine. So I went ahead and purchased this. I am so happy after installing the RAM myself. The MBP is much faster than before and applications all launch in no time, and I don't see the dreaded wait cursor anymore :). Overall very happy with the product and I will heavily recommend this to all. Been using it for 3 days now and have had no issues. The upgrade process itself was very easy going by the videos, anyone can do this :)

Rating: 5/5 Great product, fast shipment, good price January 29, 2017 Have a 2010 Mac Mini that came with 4GB of Memory. Upgraded a to 8 GB several years ago. At the time that was the most it would take. Have been thinking of getting a new Mini but they haven't come out with a new one since 2014 and no plans for one that I could find. Main reason was to get more memory. I got ad for this site, went there and discovered that with the latest OS version I could put in 16 BG. Got these, took about 5-10 minutes to install and now have 16GB. No more slowing down down to low memory. May still get a new Mac Min if they make one but no real pressure.

Rating: 5/5 Easy thx video instructions January 5, 2017 I received this product as part of upgrading my 2010 MacBook Pro. I received all my items within a couple of weeks as it had to cross the border. Duty was about $55, but even with the exchange and duties it was still a better deal than through Amazon.ca.

The installation video was very helpful. I used another computer to follow with the video. This company has been highly recommended by others who are very involved with computing, relying on them for performance. I'm very happy to have found this company as recommended by others and won't hesitate to do the same. This really helps make my investment in a Mac Product worthwhile for years to come.

Rating: 5/5 Brilliant! December 12, 2016 I've been working with Creative Cloud, Office etc on a Mac Mini mid 2010 for just over a year and the speed has been painfully slow. I'd read on the Apple site that unfortunately the RAM could not be upgraded to anymore than 8GB and upgrading to a SSD looked very complicated for this model. I was 'making do' until I saw a press release from MacSales saying they believed that it was possible to upgrade the RAM for this model.

I bought from MacSales since they are a reputable business and I've had trouble in the past with parts from eBay that didn't work. I fitted the RAM very easily and low and behold the upgrade indeed doubled the speed on my machine.

Needless to say, I'm thrilled! This upgrade has saved me the money I would have spent on a new machine, and the hours spent transferring over all the data / license keys / setting it up.

It has been brilliant, I don't often post reviews but I wanted to in case anyone has any reservations about it working, in light of Apple's advice. It definitely can be upgraded and very noticeably speeds the system up. It's as fast as my laptop which has a SSD. Thank you!

Rating: 5/5 Boosted the speed of my white 2010 model MacBook! November 26, 2016 I bought a white MacBook in August 2011, the discontinued model. It came with 2 GB of RAM. In the last 2 years, it became excruciatingly slow. I read on Other World Computing that my model (currently running the Yosemite operating system) could be upgraded to 16 GB. I was skeptical, but WOW! So much faster! I wish I had upgraded long ago. It was a great price and it has extended the life of my white MacBook. Great buy!
